The lower perforated diaphragm O is attached to a shaft, B, adapted to be rotated, when required, by clutch-gearing l), or other means, the said diaphragm being made with radial slots 0, as seen in Fig. 2, or any openings which will cause the rotation of the diaphragm to graduallydischarge the meal through it, when the treatment of the meal in the vat. is completed. I

Beneath the diaphragm C is a series of plows, or oblique wings O, to carry the meal to the central.discharge-orifice. The lower end of the shaft B carries a screw, E, to forward the meal downward through the discharge-tube orhopper F. This discharge-tube or hopper F is guarded by a sliding or gate valve, G, the construction of which is best shown in Figs. 3 and 4. It is opened and closed by a screw, H, and is fitted to slide in guides I I, which are supported by springs J J, to hold the gate in contact with its seat while it is being opened'or closed. While it, remains shut, and the meal is being treated,

the gate is held rigidly up to its seat by an eccentric, K, operated bya lever-shaft, L.

may be placed directly over the separator withp out the interposition of a conveyer, M N.

The shelf or shelves P are warmed by water contained in the chambers 19 within them, and supplied by the condensation of steam which is introduced through branches q of the main steam-pipe'Q. The requisite degree of heat is thus constantly maintained, and the surplus water overflows through the branches 0' into the water-discharge pipe R.

, In the illustration given in Figs. 1, 5, and 6,

the shelves P are provided with aperturesv pl and p alternately located at the center and circinnference.

S is an axial shaft, to be driven continuously, carrying at its lower end a dischargingscrew, 8, and above each of the shelvesP one, two, or more horizontal arms, T, in which are mounted left and right hand plows or oblique wings t and t the plows it being adapted to move the material in a regular and gradual manner inwardly toward the central openings main vapor-pipe V which leads to the condenser.

The condenser may be constructed with a worm, W, placed within a cold-water chamber, w, or in any other eflicient manner, and

is located below the level of the separator, so that the vapors, which are quite heavy, may

flow freely to the condenser, and not collect with any pressure within the separator.

. In Fig. 7, the conveying-screw X, working ,within a pipe, Y, which is surrounded with a hot-water jacket, X constitutes a separator,

which may be used in connection with or instead of that shown in the upper part of same fi ure.

The screw and the jacketed tube within which it wor (s, may be made of any required length, so that the meal entering from the vat orvats, at or near one end of the tube, will pass gradually along its entire length, and be discharged in a perfectly dry state at the other end, while the evolved vapor passes off in the other direction to the condenser W.

Operation: The vats A A being filled with meal or other material to be treated,bisu1phide of carbon or other suitable chemical is introduced at a, and, rising through the perforated bottom 0, permeates the entire mass of meal, completely removing therefrom its contained oil. The combined chemical and oil, rising through the diaphragm e, overflows through the pipe I) to the oil-separator, which may be constructed as described in an application for Letters Patent which I have made, of even date herewith. As soon as the chemical comes over without oil, indicating that the oil is all removed, the influx of chemical is stopped by closing the cook a, and that remaining within the vat is drained off as completely as practicable by opening the cock to; or separate pipes may, if preferred, be used for introducing the chemical and draining it off. 7

When the dripping is done, the eccentric K is retracted and the gateGopened. The shaft B is then rotated to turn the perforated bottom Ofcausing the meal to descend through the slots 0 tothe action of the plows G and screw E. The entire contents of the vat are thus discharged into the conducting-tube'or hopper F, and by this conveyed to the separator,'through which they are passed with a gradual movement, by mechanism substantially as described, over surfaces heated to a moderate degree, and are discharged continuously, in a perfectly dry state, ready for any 1 substantially asexplaiuedf use forwhich they may be designed, either as food, orfor brewing, distillation, or anymanufacturmg purpose.

Thevat being emptied, the cap f c is removed and a new charge introduced, when the work: proceeds as before,

. In Fig. '1 the vat A is shown openbelow, as for the discharge of a meal which has been divested of its oil, and the vat A closed as when the work of removing the oil is in progress.

It is the intention to discharge the vats successively, employing a sufficient number of vatsto keep up a constant supply of meal to the separator, and thus make the operation continuous, as before stated.

a What I claim as my invention isp 1." In combination 'with a separator for evapcrating the chemical fromthe material treated,

I and a condenser for receiving the chemical, a treating-vat, arranged to allow a portion of the chemical to be drained orl dripped before the contents are discharged for drying.

2. A vat constructed andarranged to allow chemical to rise through the meal or other material, the mingled oil and chemical to flow off at top, andthenithe chemical to be drained ofi' "or partially drainedoif at bottom, and the treated material to be subsequently discharged without exposure to theairuntil the chemical has beenseparated therefrom by evaporation,

Avat having a perforated bottom, dia

phrag'm, drip-pipe, and any arrangement for discharging the contents without exposure to theair.

4. A vat having, in connection witlia-discharge-opening or openings at or near the bottom, a rake, screw, or other mechanical appliance for discharging the treated material into a receptacle or drying apparatus, substantially as described.

5; The gate-valve G, or any substantiallyequivalent valve or gate, kept vup to its seat bysprings to preventthe entrance of meal between the valve and seat, as set forth.

,6. The eccentric K, in combination with the gate-valve G, or its equivalent, substantially as described.

.7. In combination with any arrangement of -vats or receptacles for treating vegetable or a other matter with a chemical for removing oil, an apparatus for separating the chemical by evaporation, having a conveyer or conveyers for moving the meal over heated surfaces, andafterward discharging it therefrom, without external openings through which vapor will escape. I v

8. An apparatus by which meal is conveyed over a heated surface by a mechanical contri vance such as will move the meal along a fixed course and discharge it at a desired point or points, in combination with oil-extracting vats and vaporcondenser of any suitable form.

-9.The relative arrangement of the separator and condenser, substantially as described;

with the latter chiefly or wholly below the level of theformer, for the purposes explained: j
